The number of research papers available today is growing at a staggering rate, generating a huge amount of information that people cannot keep up with. According to a tendency indicated by the United States’ National Science Foundation, more than 10 million new papers will be published in the next 20 years. Because most of these papers will be available on the Web, this research focus on exploring issues on recommending research papers to users, in order to directly lead users to papers of their interest. Recommender systems are used to recommend items to users among a huge stream of available items, according to users’ interests. This research focuses on the two most prevalent techniques to date, namely Content-Based Filtering and Collaborative Filtering. The first explores the text of the paper itself, recommending items similar in content to the ones the user has rated in the past. The second explores the citation web existing among papers. As these two techniques have complementary advantages, we explored hybrid approaches to recommending research papers. We created standalone and hybrid versions of algorithms and evaluated them through both offline experiments on a database of 102,295 papers, and an online experiment with 110 users. Our results show that the two techniques can be successfully combined to recommend papers. The coverage is also increased at the level of 100% in the hybrid algorithms. In addition...

The number of research papers (128 papers) on mycotoxins published by Brazilian researchers in 1991-2000 surpassed the total number (85 papers) published in the preceding three decades (1961-1990). Thirty percent of the papers surveyed mycotoxins in foods and feeds. AFs in peanut and peanut products continued to be alarming, and high incidence and levels of FBs in corn and corn products also appeared as a serious problem. Contamination with other toxins, such as ZEA, OTA and trichothecenes, was low. Occurrence of AFM1 in milk and dairy products and patulin in apple juice needs to be verified as the results are somewhat diverging. Work on analytical methods, mycological examination and toxic effects constituted 16, 13 and 13%, respectively, of the published papers in the decade assessed. Attempts to find means of preventing/controlling fungal growth and mycotoxin production notably increased, making up 27% of the papers, including investigations on influencing factors (e.g. genotype resistance, water content/a w, relative humidity, temperature, presence of metals, type of soil, mite infestation) and antagonistic potential of other microorganisms against mycotoxin-producing fungi. Effects of plant extract, flavonoids, fungicides and other chemicals...

AIMS--To examine trends in necropsy based research output for a period of 27 years during which there has been a progressive decline in clinical necropsy rates. METHODS--The numbers of necropsy based research papers published between 1966 and 1993 were determined using the CD-Plus Medline computed literature database. RESULTS--The number of necropsy based research papers containing necropsy or a synonym in the title increased by 220% between 1966 and 1993. When papers including necropsy or a synonym in the abstract, but not in the title, were included, the proportion of all indexed papers increased from 0.35% in 1975, when abstracts were first included, to 0.53% in 1993. Analysis of the subject material indicated that necropsy based research has constantly reflected trends and advances in clinical medicine. Neuroscience related research represented the largest subject category which may reflect the difficulties in obtaining human tissue from sources other than necropsy. CONCLUSIONS--The modern necropsy continues to provide valuable information for all clinical and laboratory based disciplines. The decline in clinical necropsy rates would not yet appear to have undermined the contribution of the necropsy to research.

To identify where the quality research activity has been and is carried out in Korea, and to examine to what extents Korean medical colleges play leading roles in the production of international research papers, we investigated the publication productivity of Korean medical colleges and their medical departments as measured by the number of papers published in foreign journals indexed in MEDLINE. The 12-year period from 1988 to 1999 is covered. A total of 4,881 papers is published in MEDLINE foreign journals by the researchers in Korean medical colleges during the period. The production of MEDLINE papers are concentrated in a few universities. More than 60% of MEDLINE foreign journal papers is published by top five universities 25% by Seoul National University, and 15% by Yonsei University. The newly established medical colleges at the University of Ulsan and Sungkyunkwan University produced outstanding numbers of papers in less than ten years. Radiology has led the internationalization of Korean medical papers. It was the most productive specialty identified in this study. The productivity of Internal medicine is on the rise from the mid-1 990s, and the field began to produce the most number of papers since then.

The University of Rochester’s River Campus Libraries are known as innovative and forward thinking, especially in the areas of reference outreach, online catalogs, institutional repositories, and Web-based services. Still, the library staff wanted to do more to reach students and their instructors in support of the university’s educational mission. But to do more, we realized we needed to know more about today’s undergraduate students— their habits, the academic work they are required to do, and their library-related needs. In particular, we were interested in how students write their research papers and what services, resources, and facilities would be most useful to them. As Katie Clark, director of the Carlson Science and Engineering Library, remarked early in this project, “Papers happen,” but we did not know how they happen. Thus, in the summer of 2004, a group of librarians and the River Campus Libraries’ lead anthropologist met at a park on the shore of Lake Ontario for lunch and a discussion of some research we might do to enlarge our knowledge of undergraduate work processes. Many of us had participated in a previous study, supported by a grant from the Institute for Museum and Library Services...

Statisticians use the Internet and the World Wide Web to exchange e-mail and to view, retrieve and distribute research papers, data sets, source code and other materials. In addition to the text, data, and graphs in paper reports, electronic papers can include sound, animation, video and other computerbased media products that can improve the presentation of the results. Recently it has become possible to embed executable content - programs -- into electronic documents. A statistician can now write computer programs to perform calculations described in the paper, embed the code in the paper, and distribute the paper over the Internet. Any reader can execute the code locally and interact with the program. This capability transforms a static presentation of research results into a presentation that can be dynamic and interactive. This paper describes how the new capability can change the way statistical research is conducted. An illustration is given from the vision research field. In this real-life problem, researchers need to estimate the parameters of the ellipses that best fit particular data sets. Our software allows any researcher with a browser to compute the parameters, get estimates of standard errors, and draw pictures to illustrate the quality of the fit. p. 3.

(Excerto) This e-book presents a selection of the research papers presented at the 5th European Communication Research and Education Association (ECREA) Conference in Lisbon, November, 2015. The book reflects the work of researchers within the Organisational and Strategic Communication (OSC) Section of ECREA from different backgrounds and higher education institutions in Europe and highlights the diverse professional and scientific interests of the Section. At the 5th ECREA Conference, the OSC Section selected almost 50 papers from the 90 submitted abstracts, which were organized into two specialist panels (“Government Public Relations in Europe: Critical Perspectives” and “Inconsistences Organizational Communication”), eight parallel sessions and one poster session. Those papers selected for Lisbon 2015 made a valuable contribution to key contemporary communications debates and issues. The peer reviewed papers presented in this volume share findings and “state of the art” critical reflections, which address the core objective of the Organisational and Strategic Communication Section of ECREA. They also continue the tradition of the promoting scientific knowledge in our broad and diverse field of research...

This evaluation of World Bank research between 1998 and 2005 was carried out by a panel consisting of Abhijit Banerjee (MIT), Angus Deaton (Princeton, chair), Nora Lustig (UNDP), and Kenneth Rogoff (Harvard.) The panel selected a large random sample of research projects, which were read and assessed by a team of 25 evaluators. Panel members also solicited views from current and past Bank staff, as well as from policy makers and academics in developing countries. Based on the evidence the authors assembled, the interviews the authors conducted, and their own consideration, the panel concluded that the World Bank needs a research department, and that its research needs cannot be fully met by hiring in from the outside. Research is a central part of quality control in the Bank, and is crucial to its claim to be 'Knowledge Bank.' Without a research-based ability to learn from its projects and policies, the Bank could not maintain its role as the world's leading development agency. The 2.5 percent of its administrative budget that the Bank spends on research is surely too low given the multiplicity of tasks that research is expected to fulfill...

ECER 2014 "The Past, the Present and Future of Educational Research in Europe" will take place at the University of Porto from 1 - 5 September 2014.; Between 2007 and 2012 an action research project named RRC (Researching for a Relevant Curriculum) was implemented in the Azores, Portugal. It was conducted by a team that included university scholars and teachers from elementary and secondary schools. The focus of the collaboration was the lack of interest shown by some students with regard to the school and the curriculum. This paper examines two forms of teacher collaboration observed in the context of RRC: a weaker form, based on the provision of suggestions on new teaching strategies and related aspects of the colleagues' work, and a stronger form, based on assistance and some joint work. For example, one teacher took notes of a colleague's behavior in the classroom in order to help her identify aspects that needed improvement, and other specific research tasks – like interviewing children and writing research papers – were sometimes done together by researchers from the university and elementary school teachers. Overall, collaboration increased in the last year of the project's implementation, which will be discussed in terms of (1) the possible relation between this fact and a reorientation in the team's approach to the action research process...

‣ Learning Biology through Research Papers: A Stimulus for Question-Asking by High-School Students

Question-asking is a basic skill, required for the development of scientific thinking. However, the way in which science lessons are conducted does not usually stimulate question-asking by students. To make students more familiar with the scientific inquiry process, we developed a curriculum in developmental biology based on research papers suitable for high-school students. Since a scientific paper poses a research question, demonstrates the events that led to the answer, and poses new questions, we attempted to examine the effect of studying through research papers on students' ability to pose questions. Students were asked before, during, and after instruction what they found interesting to know about embryonic development. In addition, we monitored students' questions, which were asked orally during the lessons. Questions were scored according to three categories: properties, comparisons, and causal relationships. We found that before learning through research papers, students tend to ask only questions of the properties category. In contrast, students tend to pose questions that reveal a higher level of thinking and uniqueness during or following instruction with research papers. This change was not observed during or following instruction with a textbook. We suggest that learning through research papers may be one way to provide a stimulus for question-asking by high-school students and results in higher thinking levels and uniqueness.

The curricula vitae of four candidates for a professorial appointment at Athens University were examined to estimate the actual contribution of each candidate to the papers of which he was a coauthor. A total of 879 research papers by the four candidates were analysed in terms of the number of authors, the sequence of names, and the year of publication. The four authors presented 364, 349, 96, and 70 papers. If an equal contribution of all coauthors is assumed, the actual number of papers (all papers divided by the number of authors), is about 106, 83, 28, and 26, respectively, so that the rank of the four candidates did not change. On the assumption that the contribution was related to the candidate's position in the order of the coauthors' names, the numbers of papers were corrected to 84, 95, 26, 33 using one statistical method and to 88, 94, 28, 31 using another. These assumptions may not be valid, however, especially as the last author may be more important than the intermediate ones. It is suggested that the journals require authors to state their specific contribution to a paper, such as original idea, planning, collecting data, writing up, etc.

BACKGROUND. An increasing number of people involved in medicine are under pressure to publish research, but there is little understanding of how to describe structured writing. AIM. This paper aims to describe the structure of original research papers published in the British Journal of General Practice with a view to providing insight into the nature of such analyses, and particularly to help researchers and trainers to write and teach writing more successfully. METHOD. A sample of 50 original papers published in the Journal between January 1989 and March 1993 were examined. The papers were subjected to a form of 'move structure analysis', a technique used in applied linguistics; move structure analysis assigns a tentative function to a piece of text, and identifies words/phrases associated with it. To be recognized, moves thus identified had to occur in the same section of the paper in 65% of the corpus, and/or appear in the same order relative to other moves in 50%. RESULTS. Fifteen moves were identified, four in the introduction, three in the method, and four each in the results and discussion. These moves functioned, for example in the discussion, to state limitations and defend successes; describe achievements; contextualize procedures and findings; and offer recommendations. Frequency scores ranged from 66% to 100%...

To support nanocrystal device development, we have been working on a computational framework to utilize information in research papers on nanocrystal devices. We developed an annotated corpus called “ NaDev” (Nanocrystal Device Development) for this purpose. We also proposed an automatic information extraction system called “NaDevEx” (Nanocrystal Device Automatic Information Extraction Framework). NaDevEx aims at extracting information from research papers on nanocrystal devices using the NaDev corpus and machine-learning techniques. However, the characteristics of NaDevEx were not examined in detail. In this paper, we conduct system evaluation experiments for NaDevEx using the NaDev corpus. We discuss three main issues: system performance, compared with human annotators; the effect of paper type (synthesis or characterization) on system performance; and the effects of domain knowledge features (e.g., a chemical named entity recognition system and list of names of physical quantities) on system performance. We found that overall system performance was 89% in precision and 69% in recall. If we consider identification of terms that intersect with correct terms for the same information category as the correct identification, i.e....

This study is designed to identify constraints and potential solutions for improved performance and quality of digitally printed papers. The targeted market segment is high-end digital production in the U.S. In the first phase a survey of print providers has been conducted, the sample drawn from the network of printing companies currently engaged with Printing Industry Center research activities. The second phase will be to follow up observations from the survey with a case study approach, working with both print providers and with digital press manufacturers. In order to understand the characteristics of this digital printing market segment, a demographic study of the respondent group was conducted as part of the survey. This was followed by an exploration of the considerations and paper characteristics that are involved in the paper grade selection decision. The role that paper characteristics and press requirements play in production efficiency and document quality was investigated. The change in paper costs to printers over the last few years was also explored.Specific research objectives included: identifying the paper grades commonly used for the market segment of production digital printing, identifying the number of brands used and the nature of printing companies’ relationships to suppliers...
